Reel for rod or wire

ABSTRACT

In one form of reeling rod or wire, the rod or wire is coiled in a rotating vertical axis drum with a fixed container around the drum for holding cooling liquid so that the drum can rotate below the level of the liquid and to prevent the liquid being thrown out of the drum by centrifugal force, there is an annular casing above the drum with a diameter larger than that of the drum and a coaxial fixed ring of deflectors within the annular casing. The annular casing is fixed against rotation, but can preferably be lifted up, for instance, to discharge the finished coil. The deflectors stop or slow down the top zone of the swirling liquid and can prevent or make less marked the formation of a cone shaped surface on the liquid.

The drum may have an interrupted inner wall or other guide means such as a ring of vertical rods for forming the inner edge of the coil.

It is an object of the invention to produce a reel of this type which reduces or prevents oxidation of the surface of the rod or wire, can be arranged to ensure a sufficient degree of cooling and can be arranged to prevent the cooling liquid being forced out of the reel, even when the drum is rotating.

SUMMARY OF THE INVENTION According to the present invention, there is provided a reel for coiling hot rod or wire and cooling the rod or wire with a liquid, the reel having a vertical axis rotary open top drum comprising a continuous outer casing,

a fixed open top container around the drum and arranged to be filled with cooling liquid, whereby the drum can rotate below the level of the liquid,

an annular casing above the outer casing of the drum, which annular casing is fixed against rotation and has a larger diameter than that of the outer casing of the drum,

a coaxial fixed ring of deflectors within the annular casing,

and means for driving the drum.

The deflectors may, with advantage, be in the form of a ring of radially directed, vertical plates. The internal. diameter of the ring of deflection is preferably equal to or greater than the diameter of the outer casing of the drum.

Owing to the rotation of the drum below the surface of the liquid, there is no eddy current with air inclusions such as occurs during spray cooling, and the rod or wire entering the reel is thereafter protected against oxidation. On the other hand, the deflectors which are arranged above the drum and may take the form of plates to prevent the cooling liquid from being forced up out of the drum as it rotates by the action of centrifugal force. The rotation of the liquid is markedly slowed down, particularly if the deflectors are in the form of vertical plates which are directed radially outwards. The liquid may be on a level with the plates and the plates can ensure that the surface of the liquid is stilled. One can thus avoid the formation of a high cone of liquid and avoid forcing the liquid out of the reel. The surface of the liquid can be almost flat even at the height of the deflectors, and it may be impossible for the conical flow to form.

In a further embodiment of the invention, the deflectors are held in position by an upper and a lower annulus connected to the annular casing by spacer members. These spacer members may be webs or struts. They may, however, alternatively consist of an uninterrupted upper and lower ring. An uninterrupted ring would not serve tov redirect the flow of any water caused to rise by the action of centrifugal force, but would merely serve to position the circle of deflectors with respect to the annular casing.

The annular casing, which preferably forms a single unit with the deflectors, may advantageously be able to move axially upward. At the same time, an overflow channel may be provided on the fixed container to catch the cooling liquid which flows outwards and downwards on the outside when the annular casing is lifted. At least one ram (preferably hydraulic) may be provided for moving the annular casing axially.

Since the annular casing can be sealed to the fixed container and since under operating conditions the cooling liquid is located within the annular casing, the upward movement of the annular casing can safely cause cooling liquid located above the level of the container rim to flow down into the overflow channel surrounding the container.

At the same time as the annular casing moves upwards, the coil of rod or wire resting on say a coiling plate within the drum is also able to be moved upward above the level of the edge of the fixed container, so as to be conveyed off to the side.

The upward movement of the annular casing may be omitted when the internal diameter of the deflectors is greater than that of the outer drum wall, and when the guide for the incoming rod or wire is pivotable out of the region of the drum diameter. In this case, the say coiling plate with the coiled rod or wire may be raised to the height of the upper edge of the annular casing.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be further described, by way of example, with reference to the accompanying drawing, in which FIG. 1 shows a pouring reel having a rotary rod or wire coiler drum and a fixed container, the view being in longitudinal section along the line I I of FIG. 2, and

FIG. 2 is a plan view, in partial section, of the reel.

DETAILED DESCRIPTION OF THE DRAWINGS A circular, open top container 1 rests on a fixed mounting block 2 and carries an open top coiler drum 3 which can rotate about a vertical axis. A hub 4 located below the drum 3 passes through the base of the container l and is sealed thereto by means of a sealing ring 5. The hub 4 is rotatably mounted :in the bearing block 2 by means of bearings 6 and carries on its outside a worm wheel 7 which is driven in the direction of the arrow in FIG. 2 by a worm 8.

The hub 4 contains a hydraulic lifting device which comprises a fixed cylinder 9, a piston 10 and piston rod 11. The upper end of the piston rod 11 carries a coiling plate 13 on which a coil of rod or wire 12 rests, with the plate 13 being movable upwards by means of the lifting device 9, 10, 11. The coiling plate 13 is divided by an internal wall 14 which passes through plate 13 and is itself divided into a number of separate portions. The internal wall 14 and the outer wall 3' of the drum 3 together define an annular chamber 15 which receives the coil 12 and the internal wall 14 is secured to the base of the drum 3. T

The upper edge of the outer wall of the container 1 has an annular casing 17 mounted thereon in a watertight manner, achieved by means of a sealing ring 16; the annular casing 17 is coaxial with a ring of vertical, radially directed deflector plates 1.9. The plates 19 are held in position by an upper and a lower annular plate, and are connected to the annular casing 17 by means of spacer members in the form of webs 18 on the inner side of the casing 17.

A rod or wire feed device 20, which constitutes a single unit with the annular casing 17, leads downwards at an angle into the annular chamber defined by the outer wall 3 of the drum 3 and the internal wall 14.

The container 1 is filled with cooling liquid in any suitable manner until the surface of the cooling liquid lies between the bottom and the top of the circle of deflector plates 19 with cooling liquid. An overflow channel 21 is secured around the outside of the container l. Brackets 22 are provided on the periphery of the container 1 and carry hydraulic ram units 23. Supporting arms 27 on the annular casing 17 are articulated to connecting plates 25 of piston rods 24 of the rams 23.

When the rams 23 are actuated, the annular casing 17 with the deflector plates and feed device is raised into the position shown-in dot-dash lines in FIG. 1. The cooling liquid located within the circle of plates 19 now flows into the overflow channel 21. The coil of rod or wire 12 which rests on the coiling plate 13 is raised by means of the hydraulic lifting devices 9, 10, 11 to the height of the upper edge of the container 1, when the coil 12 is able to slide sideways. In order to allow cooling liquid to flow out of the chamber below the coiling plate 13, or into the chamber, as the coiling plate 13 moves in a vertical direction, the bottom of the coiling drum 3 is provided with a number of apertures 28.
